**cusp**is adumbrated in shadowy form, in a slightly higher horizon it is visible, in a still higher horizon it is full-grown; and we honour this final stage by assigning to the animal which bears it a new specific name. - As regards the so-called hyperbolisms, observe that (besides the single asymptote) we have in the case of those of the hyperbola two parallel asymptotes; in the case of those of the ellipse the two parallel asymptotes become imaginary, that is, they disappear; and in the case of those of the parabola they become coincident, that is, there is here an ordinary asymptote, and a special asymptote answering to a
**cusp**at infinity. - Similarly a cubic through the two circular points is termed a circular cubic; a quartic through the two points is termed a circular quartic, and if it passes twice through each of them, that is, has each of them for a node, it is termed a bicircular quartic. Such a quartic is of course binodal (m = 4, 6= 2, K = o); it has not in general, but it may have, a third node or a
**cusp**. Or again, we may have a quartic curve having a**cusp**at each of the circular points: such a curve is a " Cartesian," it being a complete definition of the Cartesian to say that it is a bicuspidal quartic curve (m= 4, 6 = o, K= 2), having a**cusp**at each of the circular points. - The curve is symmetrical about the axis of x, and consists of two infinite branches asymptotic to the line BT and forming a
**cusp**at the origin. - Summits of the lower incisors, before they are worn, with a deep transverse groove, dividing it into an anterior and a posterior
**cusp**. Canines long, strong and conical.
